pypeto

pypeto is a PyQt-based application designed for managing control screens for EPICS (Channel Access and PVAccess) and LiteServer devices. The architecture is modular, allowing for easy integration of various control pages through a tabbed interface.

• Data Flow:
  • The application communicates with EPICS and LiteServer devices to fetch and display process variables in real-time.
  • Configuration files are Python scripts that define the behavior and layout of control screens.

Features:

• control of EPICS PVs and LiteServer PVs,
• tabs: several control pages can be managed from one window,
• automatic page generation for LiteServer devices,
• single configuration file can be used for many similar devices,
• configuration files are python scripts,
• snapshots: control page can be saved and selectively restored from the saved snapshots,
• embedding os displays from other programs to a range of cells,
• plotting of selected cells using pvplot,
• merged cells, adjustable size of rows and columns, fonts and colors,
• horizontal and vertical slider widgets,
• content-driven cell coloring,
• slicing of vector parameters.

Examples:

Control of a simulated oscilloscope from EPICS PVAccess infrastructure:

# Start server for a simulated ADC device 'epicsDev0'
python -m epicsdev.epicsdev -l
# Start control page ./test/picsdev_pp.py
python -m pypeto -c test -f epicsdev

Control of a peak simulator from LiteServer infrastructure,

for more detalis see :

# Start the liteServer of a peak simulator
python -m liteserver.device.litePeakSimulator -i localhost -p9701
# Start control page ./test/simScope_pp.oy
python -m pypeto -c test -f peakSimPlot -e

Two control pages in tabs:

python -m pypeto -c test -f peakSimLocal peakSimGlobal

Control of a simulated oscilloscope from EPICS Channel Access infrastructure

python -m pypeto -c test -fsimScope -e
